Cons: Looks like a toaster, slim optical drive can't be used with a CLC

I purchased the SG05-450BB to downsize my folding rig from a way-overkill 650D. I'm not running a discrete video card, so the SUGO has plenty of room for my hardware, including an Antec Kuhler 620 with push/pull fans. That gives me plenty of cooling to run my 3770K @ 4.6GHz with max temps under 80C.

For $120 with 450W PSU included its hard to beat for the price & size. If I was going to add a video-card or more robust cooling I'd consider the larger variants (SG6/7/8) in a heartbeat.
